Participation at the Public Meeting

What must I do to make a presentation at the meeting? If you would like to make a presentation at the meeting, make your request to FAA no later than 10 days prior to the meeting. Submit these requests to Mr. Marv Nuss as listed in the FOR FURTHER INFORMATION CONTACT section of this document. You should include a written summary of your presentation with a time estimate of your presentation.

Will FAA prepare an agenda? We will prepare an agenda for this meeting. To accommodate all presenters, we may allocate less time for your presentation than you requested. If you request to present after the deadline, we will schedule your presentation as time is available. However, your name may not appear on the agenda.

What if I need special equipment? You should include in your presentation request any special audiovisual equipment that you need. We will accommodate reasonable requests.


Why is the FAA conducting this meeting? There have been concerns about fatigue cracking on Cessna 400 series airplanes since the 1970s. In 1979, the FAA issued ADs to require periodic inspection of Cessna 400 series wing spars. The FAA evaluated fatigue and crack growth analysis recently performed by the Cessna Aircraft Company and determined that the wing spars of the Cessna 400 series require modification and periodic inspection to prevent in-flight wing separation. The service history includes a 1999 accident caused by a wing failure and six other incidents where cracks were found before the wing failed. To address this airworthiness concern, the FAA issued two NPRMs in May 2003 (that would supersede two existing ADs on the affected aircraft) to propose incorporating a spar strap modification on each wing spar.

Many owners of the affected aircraft were vehemently opposed to the action due to the high cost. To ensure that the public had the opportunity to fully communicate their concerns, the FAA:

  • Extended the comment period an additional 30 days beyond the initial 60-day comment period;
  • Reopened the comment period for another 60 days; and
  • Held a public meeting on March 3 and 4, 2004, in Herndon, Virginia.

After analyzing all information related to this subject, the FAA decided not to issue the new ADs as proposed. The FAA has determined that the best way to address the unsafe condition is for the FAA, the public, and industry to develop alternative solutions for addressing the unsafe condition. Accordingly, the FAA withdrew the NPRMs on May 18, 2004 (69 FR 29672, May 25, 2004) and is holding this second meeting to continue this effort.
